The multicast ipv6 boundary command configures an IPv6 multicast forwarding boundary on an interface.
The undo multicast ipv6 boundary command deletes the configured IPv6 multicast forwarding boundary from an interface.
By default, no IPv6 multicast forwarding boundary is configured on an interface.
| Parameter | Description | Value |
|---|---|---|
| ipv6-group-address | Specifies an IPv6 multicast group address. |
The value ranges from FF00::0 to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF, in hexadecimal notation. |
| ipv6-group-mask-length | Specifies the mask length of an IPv6 multicast group address. |
The value is an integer ranging from 8 to 128. |
| all | Deletes all the IPv6 multicast forwarding boundaries configured on an interface. |

Usage Scenario
The multicast ipv6 boundary command is used to configure an IPv6 multicast forwarding boundary to set the forwarding range for IPv6 multicast data packets.
Prerequisites
The multicast ipv6 routing-enable command is run in the public network instance view.
Configuration Impact
To configure multiple IPv6 multicast forwarding boundaries for different multicast groups on an interface, run this command on the interface for several times.
Precautions
Assume that A and B are two multicast group ranges to be configured with IPv6 multicast forwarding boundaries, and B is a subset of A. If A is first configured on an interface, B cannot be configured. If B is configured on the interface first and then A is configured, the configuration of B is substituted by that of A.
